The family is the basic unit of society—yet, statistically, family members are the very people who are most likely to steal the last soda from the fridge. Solidify family alliances and suss out enemies with today's Groupon: for $14, you get an all-day play pass (up to a $27.99 value) to Boomers! Choose from the following locations: Vista, El Cajon, and San Diego.

At Boomers!, thrill-seeking families and fun-enabling friends can attack a variety of appealing attractions, including mini golf, batting cages, bumper boats, and the button-mashing joys housed inside the exhilarating game room. The Vista location entertains families of sharpshooters with a blacklight-illuminated laser-tag arena before little ones climb and crawl through the Kidopolis play area. The El Cajon and San Diego locations let rivals celebrate the spirit of competition as they fly past each other in speedy go-karts or have a snail-paced Ferris wheel race at the kid's county fair. Unlimited pass holders at the El Cajon location can also scale the 32-foot-tall climbing wall, which, like America, enables citizens to climb to the top via myriad routes.

Though Boomers! sometimes features a discounted price online, this Groupon still offers the best deal available.
